Nez, who is the last surviving member of the Original 29 Navajo Code Talkers, published a memoir of his service with the U.S. Marine Corps in the Pacific Theater during World War II in 2011. The Japanese were never able to crack the code the Navajo created from their native language, turning the tide in the Pacific. For more information about the book, click here.
